In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.
Q: Question: Which of the two rock musicians that appeared in "The Secret Policeman's Ball" recorded an album first? Passage:Ball co-founder Cleese and Jones had an involvement (as performer, writer or director) in all four Amnesty benefit shows, Palin in three, Chapman in two, and Gilliam in one. Idle did not participate in the Amnesty shows. Notwithstanding Idle's lack of participation, the other five members (together with "Associate Pythons" Carol Cleveland and Neil Innes) all appeared together in the first Secret Policeman's Ball benefit—the 1976 A Poke in the Eye held at Her Majesty's Theatre in London's West End—where they performed several Python sketches. In this first show, they were collectively billed as Monty Python. Peter Cook deputised for the errant Idle in a courtroom sketch. In the next three shows, the participating Python members performed many Python sketches, but were billed under their individual names rather than under the collective Python banner. The second show featured newcomer Rowan Atkinson and Scottish comedian Billy Connolly. The Secret Policeman's Ball were the first stage shows in the UK to present comedic performers (such as Monty Python and Rowan Atkinson) in the same setting and shows as their contemporaries in rock music (which included Eric Clapton, Sting and Phil Collins). After a six-year break, Amnesty resumed producing Secret Policeman's Ball benefit shows which were held at the London Palladium in 1987 (sometimes with, and sometimes without, variants of the iconic title) and by 2006 had presented a total of 12 such shows. The shows since 1987 have featured newer generations of British comedic performers, such as Stephen Fry, Hugh Laurie, and puppets from the satirical TV show Spitting Image, with many attributing their participation in the show to their desire to emulate the Python's pioneering work for Amnesty. Cleese and Palin made a brief cameo appearance in the 1989 Amnesty show; apart from that, the Pythons have not appeared in shows after the first four."
